Application filed November 4, 1911. Serial No. 658,570.

To all whom it may concern Be itknown that I, LUL'IS A. HILL, a citizeirof the Ynited States, residing at ll'nsliington, in the District of Columbia, have invented certain new and useful 1mproveinentsin Motor-Vehicles, of which the following is a specification.

My invention relates to improvements in motor vehicles, and it consists in the. con-- ning gearby resilient supports between said body and gear; ivhereb vthe inertia of the resiliertl v connected body acts to yieldinglv resist shifting of the drive mechanism reizrtive to the running gear, and to minimize the angel swing of the transverse, Garden drive-s rafts.

In the accompanying drawings, forming a part of this application. and in which similar reference symbols indicate corresoonding parts in the several views: Figure the chassis and drive mechanism resilientljr supported for independent relative movement on the" running gear; Fig. 2 is nnenlarged detail section on 1; Fig. 3 is a. rear elevation of the construction shown in Fig. 1; Fig. i is a rear elevation, illustrating a modified construction; Fig. 5 is a rear elevation, illustrating it further modification; Fig. 6 is an enlarged detail-section, on the line 66 of Fig. 5, and Fig. 7 is a plan view of the construction shown iii-Fig. G. p

Referring to the drawings, 1' and 2 indi cate rigid axles curved to clear the drive mechanism and connected oft-center at. and at to the hubs of ground Wheels 5; thrust ineinhers 6 bein connected to the fiXlGS'l;

and, 2, a.nd constituting with the letter 21 st-run n"? gid axle frame. The forward ends of the members I provided with a fragmentary plan view, illustrating the line 2-2 of Fig.

tor independent relutiveg head 7, which is supported for universal movementby {i bell-and-socket joint secures to the casing 8 of the propeller shaft 9 convenient assembling of the universal joint),-

the head? is provided with a, key-hole slot 10 for insertion of the ball 11, and with a socket plug 12 threaded-in a split portion of'said head, which is apertured at 13 to ceive a clamping bolt. A Y

A ,voke 14 on the forward end drummeing 8 is pivoted at 15 ton cross-member iii of the chassis, in line vvithfthe nsnal uni-. vesnl joint 17 .of the propeller shaft: 9. have shown the yoke 1-1 and ball 11" formed. integral with a sleeve 18 Which-is rigidly secured to the propellenshaftcasing 8. v

In the abo ve described construction, nil driving action ofv the ground Wheels 5' is trn ismitted directly through a rigidexle frame, which is supported "for universal movementrelative to the chassis and. the drive mechanism. Y

The differential gear 19 is resiliently sup ported on the axle frame by one or more springs 20 carried by sleeves 21 slidablymounted on the axles 1 and 22' nuxilitiry orbuffer springs 22 being confined between said sleeves 21 and collars 23 on the axles,

for v'ieldingl v maintaining said sleeves in normal position and resisting shifting of the difl erential gear from central positions" I have shown transversedrive-shafts, 28 of known type. The chassis is resi-lirintly sup-. ported on the difierential-"IQ by a. spring 24, which is connected to the longitudinal chassis members 25 by links 26po sitioned to engageyielding buffers 27 for limiting and cushioning their extreme swing. This constitutes an improved construction, in

which the buffer. springs 22 and the mass of the vehicle body act to yieldingly resist shifting of the resiliently-supported difi'erential-relative to the running g ar; thereby minimizing the angular deflection of the transverse drive-shafts 28, and insuring *a steady and eiiicient drive under all practical conditions. v v

Fig. 4 illustrates a modification, in'which the chassis-is supported on the. axle frame; by any usual form of side-springs 36. vThe springs 30" cerried by sleeves 31 slidz bly differential 29 is supported by one or-niore Y mounted on the'axle frame; auxiliary springs. 32 being confined between said sleeves 31 and collars 33 on said frame- The chassis is ad.-

dition'ally supported by ,a'leaf spring 34:"

connected thereto by links .35 and carried by the differential 29.

Fig. 'illustrates a modification, in which the'chassis is supported on the axle frame by side springs 36 ;the differential being resiliently suppo-rtedby a spring 37 carried by sleeves 38 slidably mounted on saidframe in engagement with buiier springs 39..

'In this construction, arched brackets 40 are secured to the axles land? and provided with ears 41, on which is pivotallyjsupported' a seat 1 shaft drive under 42 for said side spring; For convenience in assembling, the: bracket 40 is shown formedin two parts which are rigidlysecured to the axles by bolts i3 extending therethrou'gh and 7 through clamping plates 44: bearing on said" -My 1'nvent1on provides an improved construction, in whichtlie dr've mechaniSm and vehiclebody are resille'nt y supported for in-, dependent relative movement'on a ri Td axle framey which latter 'is connected or free unii ersa l movement relative to said meclm; nism and body; thereby eliminating all troublesomev dead weight on the running gear,andinsuring angeflicient and steady all -.conditions.
